Board sailing has gained enormous popularity. More reservoirs in the summer “bloom” her bright triangles. However, in calm weather, the wind and their sails are on the coast are mostly idle. And then athletes should remember about one more wonderful kind of water sports — rowing.
Recently we met with a model glider class Ä1. In the design of its supporting planes, and stabilizer are widely used Styrofoam, which greatly simplifies the manufacturing technology was for the benefit of the strength characteristics of the individual elements.
Harvest on record was for the Soviet rocketmodeler 1987. The strongest competition to our sportsmen managed to make a number of amendments to the lists of the highest international achievements. It is noteworthy that all records — at the height of the flight models.
We can safely say that the interest of model aircraft to jet technology continued unabated ever. Until recently, however, attempts to create flying machines with jet propulsion was only occasional, experimental and research character. Of course, affected by the absence of these turbojet engines in model performance (on the serial production of the isolated supercomplex samples seriously can not speak).
We offer modelers design developed and successfully tested Czechoslovak athletes. The basis for its design was the model class F1E, with which the author is an engineer Ow. Valens was in the recent past, the champion of Czechoslovakia. New electrolyser, named “Mamba” (the African name of a small moving extremely poisonous snakes), helped Czechoslovak athlete to become a gold medalist of the national championship and in the class FSR. At the same VL. Valenta believes that despite the specialization of a new model for long races, it has preserved the “hereditary information” and can be successfully used in the RC electric class F1E. It is enough just to increase the number of batteries and to install a more powerful motor. Basically the same option (FSR) applied a set of twenty Nickel-cadmium batteries of the Japanese firm “Tamiya” and the engine the “Mabuchi 540”.
Among the priority directions of search to achieve the best results in athletes performing in class gliders F1-A, now in a special place is dinamalar — because of its effectiveness and opening new possibilities. And the point here is not only to guarantee additional 10-15 metres in height at the start, immediately after disengagement of a rail. Provide diametrom growth lead to qualitative changes in the tactics of the competition, greatly expanding the possibility of falling in the thermals. Because every additionally recruited a meter of height increases the influence of ascending streams.
An example of a creative approach to the creation of modern sports self-similar techniques can be aircar class AC-2 motor with a working volume of 2.5 cm3. Extremely simple, but thought out to the last detail, the design speed has allowed its Creator, student of the Kharkiv school of Constantine Chistova three times to climb on the highest step of the podium at the “high” competition in this class. It should be noted that reached the championship of the USSR 204,731 speed km/h was actually a record and at the same time… unattainable. K. Chistov, the result not only exceeded to date, but even the barrier of 200 km/h is not yet amenable to young athletes.
To design and manufacture a racing car that would satisfy all the requirements of the sport today — Oh, how difficult! To do this, the athlete has to be both a competent designer, and technologist, and specialist in materials science, and machine operator-universal.
Even on these racing yachts there is a continuous struggle to reduce weight. It is known that any extra pounds at least for a little bit but increases hydrocortisone fragile vessel due to the precipitation and growth of the wetted surface of the hull. And when it comes to model and conditions, it is already possible to say that relief even ten grams is the achievement.
The idea is to make motonarty, so that they could ride on soft snow, took possession of me for a long time, fifteen years ago. But to get to work in no hurry, carefully pondered, what I would like to see your snowmobile. So gradually the mind has developed a structural diagram of a propulsion device in the form of two blocks of the ski, light surrounded the track.
